Abstract
Nanoscale structural modulation with the disordered intergrowth of three- and four-layered Aurivillius phases gives rise to the ferromagnetic clustering of the FeO<sub>6</sub> and CoO<sub>6</sub> octahedra in cobalt-substituted Bi<sub>5</sub>FeTi<sub>3</sub>O<sub>15</sub>-derived compounds.
